How CertainTeed Products Fail and How We Fix Them
CertainTeed makes solid insulation products, but every material breaks down eventually. Here’s what we pull out of Garden Grove attics most often, and what we do about it.
- CertainTeed InsulSafe SP fiberglass blown-in settles and loses loft. After 15 to 20 years in a hot attic, the binders break down and the material compacts. You end up with R-19 performance out of what was originally R-38. We remove the settled material and install fresh blown-in at the correct depth for your ceiling, verified with a depth gauge rather than guesswork.
- CertainTeed OPTIMA blow-in fiberglass absorbs moisture from roof leaks. This line is dense-packed and holds water against ceiling drywall longer than loose-fill alternatives. We see it sagging and staining in West Garden Grove homes with aging shake roofs. The fix is full removal, air sealing the ceiling plane, and then reinstalling new material once the leak source is confirmed fixed.
- CertainTeed DryRight fiberglass batts can trap rodent nesting debris. Batts give pests a ready-made burrow. In the Euclid corridor’s older ranch-style homes, we regularly remove DryRight batts that look intact on top but are riddled with tunnels and droppings underneath. Removal includes full sanitation, not just replacement.
- CertainTeed insulSafe SP in vented attics picks up wind-driven dust and fireplace soot. Vented attics in Garden Grove pull in particulate from the 22 freeway corridor and from older chimneys. The insulation turns gray and loses its fire-retardant surface in spots. Vacuum removal restores the attic to a clean baseline before we re-insulate.
- CertainTeed MemBrain smart vapor retarder fails when installed backward. We’ve opened enough walls to know that a reversed MemBrain sheet traps moisture in the cavity instead of letting it dry. The result is musty insulation and sometimes mold on the backside of the drywall. Our techs remove the affected material, correct the vapor profile, and reinstall to CertainTeed’s installation spec.
Our CertainTeed Insulation Removal & Replacement Process
We treat your CertainTeed removal like a real project with a clear start, middle, and finish. Here’s how it goes.
- 1
Call and talk to a person. You describe what you’re seeing: damp drywall, rodent activity, hot rooms, or dust from ceiling fixtures. We schedule a walkthrough, usually within a couple days for non-emergency work.
- 2
Attic inspection with photos. Neil Ashford or one of our lead techs goes up with a moisture meter, a depth gauge, and a camera. You see exactly what we see.
- 3
Material decision: remove all or replace in sections. If insulation is wet, pest-contaminated, or dust-saturated, we recommend full vacuum removal. If only one bay is compromised, we say so and quote the smaller job. No upselling.
- 4
Vacuum removal with HEPA filtration. Our truck-mounted vacuums pull old CertainTeed material out through a sealed hose. Dust stays out of your living space. We bag and haul everything same day.
- 5
Air sealing before new material goes in. With the attic empty, we seal top plates, can light gaps, and wire penetrations. This step doubles the comfort payback of your new insulation.
- 6
Fresh insulation installed and the 90-Day Done Right Promise kicks in. We document depth and coverage before we leave. If anything isn’t right within 90 days, we make it right.

FAQs
Replacing failed insulation does not void a product warranty, and if the material has failed due to a defect, CertainTeed’s warranty may cover the material cost. We document the failure with photos and moisture readings so you have a clear record for any claim. Call (657) 213-3642 and we’ll walk you through what you’re looking at.
Most attics under 1,500 square feet are fully removed and re-insulated the same day. We arrive with the right vacuum rig and enough material on the truck so we’re not making you wait on a second trip. If you need it done sooner, we can often schedule within the week.
Adding new insulation on top of failed insulation is cheaper in the moment and more expensive long-term. Wet, rodent-damaged, or dust-saturated material buried under new fiberglass still holds moisture and odors. We only recommend full removal when the existing material is compromised, and we’ll tell you honestly if topping off is fine.
If it’s an emergency, like a ceiling leak soaking your insulation or a pest problem in the attic, call (657) 213-3642 right now and we’ll tell you our next open slot. We answer live 24/7, and we can often send someone the same day for urgent situations.
CertainTeed has sold vermiculite insulation in past decades, and some vermiculite from that era contains asbestos. We do not disturb or remove vermiculite without first having it tested by a licensed lab. If you suspect vermiculite, we’ll help you identify it and connect you with the right testing resource before any removal begins.
